Russ,

Thanks for the quick reply. Sure I can call in tomorrow. I treated my tank yesterday with Flatworm Exit, and I am going through all kinds of heck. I will be making water all night to try and get a 100g change in tomorrow. I have a pretty packed schedule, but I will call in between stops. I have a inline dual test meter. The DI resin is changing color in the second DI chamber, I assume my first chamber may be packed too tightly?
